Three types available for different purposes! A plug that reduces labor for piping pressure tests.
Achieve reliable sealing even in high-pressure environments! Significantly reduce labor and costs during pressure testing.
By utilizing pressure test plugs from Curtis Wright in the United States, the man-hours required for pressure testing can be significantly reduced. We introduce three types of plugs for different applications. ● For closing pipe ends: Grip Tight ● For flange local use: DBB plug ● For flange local use: High lift flange plug 【Features】 ■ Grip Tight Can seal up to high pressure (maximum 96MPa) simply by attaching the plug No need for a series of tasks such as cap welding/cutting/preparation Reusable ■ DBB Plug Allows simultaneous isolation of the upstream side and pressure testing of the weld point Pressure testing can be performed locally only at the welding point → Achieves reduction in media volume and simplification of construction ■ High Lift Flange Plug Allows purging during welding and upstream monitoring Compatible with various flange shapes (neck flanges, slip-on, etc.) Pressure testing can be performed locally only at the welding point → Achieves reduction in media volume and simplification of construction *For more details, please download the PDF or feel free to contact us.
